, COVER FOR PRESERVING JARS.

Specification of Letters Patent. Patgntgd A 1922 Application filed August 25, 1920. Serial no, 406,0 13.

T 0 all whom it may concern: I

Be it known that I, JAMEs H. PAIGE, a citizen of the United States, residing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Covers for Preserving Jars, of which the following is a specification.

Glass covers for glass fruit jars as at present furnished to the trade have several defects. Glass jars and covers are molded and as accuracy is impossible, allowance'as to dimensions is made, for otherwise many of such covers would not'fit the jar. This necessary ov ersize results in manyv of the 'covers being so loose on the mouth of the:

jar that they can shift laterally across the mouth until the inner or upright wall of the cover strikes the extreme upper part of the jar around which the usual rubber gasket is placed.

Consequently the ordinary glass cover for a fruit jar permits the gasket to distort or squash so that imperfect or unsatisfactory sealing results. The ordinary cover also requires much patience and great effort to effect its removal, after sealing, and the unsealing frequently results in chipping, splitting, splintering or cracking of the cover and mouth of the jar, which destroys their usefulness and also may necessitate the loss of the contents of the jar.

My object is to overcome the foregoing and other defectsinhering in preserving ar covers as at present known to the art.

My improvements comprise an inner annular ridge adapted to rest upon and seal the gasket, and an outer marginal part or edge on the cover which may be either annular or provided with notched portions, located in a plane below the inner annular ridge and arranged to overhang the mouth of the jar. The sealing is effected entirely by the inner annular ridge; the overhanging, lower peripheral part of the cover serves as an abutment to prevent lateral displacement of the cover and gasket and hence does away entirely with the squashing action hereinbefore referred to. Furthermore, the outer or peripheral portion of the cover enables the latter to be easily loosened from a jar which has been sealed and entirely obviates all danger of cracking, splintering, chipping or otherwise injuring either the jar or the cover.

A modification of the cover wherein parts of the peripheral portion are omitted, enables theperson'sealingthe jar to engage her thuinb with "the wire, binding lever or the 1 like, when pressing the same downwardly in the operation of sealing.

lily invention has the further advantage.

that inasmuchas lateral displacement of the rubber gasket is prevented by reason ofthe improved form of the cover, there may be used a narrower gasket than is at present employed, thus lessening the expense for gaskets.

An ordinary jar, such as is commonly used for preserving, is shown at 1, the same being provided with a mouth 2 surrounded by 1ledge or channel 3 for supporting the gas- :et 4:.

My invention enables a. gasket to be used which is considerably narrower than the gasket commonly employed on preserving jars, thus saving in the aggregate considerable expense.

Any ordinary or preferred bail 5 and operating member 6 may be employed.

The cover 7 is provided with a ridge 8 with a central depression 9 of the usual form. On its under side the cover has an annular ridge 10 which is adapted to telescope over the mouth of the jar and to bear on the gasket. The outer edge or peripheral portion of the cover is in the form of a bead 11 which is located in a plane lower than that of the annular ridge or corrugation 10 and said bead is also located beyond the neck of the jar. As a result of this construction there exists an annular space or groove 12 when the cover is in position and the jar is sealed, enabling a fork, knife or any ordinary culinary implement to be readily introduced for the purpose of releasing the cover when the jar is to be opened. When the cover is locked in position the inner annular ridge presses firmly against the gasket '4:

and the outer orsperipheral "bead-11 serves as an abutment for the gasket and thus prevents lateral shifting of the coi er 'and hence does away entirely With the distortion of the gasket and the squashing actionhereinbefore referred to. The result isa perfect seal and yet the cover can be'quiekly and.
